BOX COLLAPSING-AND PACKING MACHINE.

r :A pncatiunmed April'19,'19 23. "Serial No. 1633;250.

T o all whom it may ooncerw' Be 1t known that LCHARnEs'F. RAYNAUD,

a citizen of the United "Statesyresidin'gatcollapsing-paperboxes for shipping-and for' pl-aeing the collapse'd boxes 'in a bundle' 'for fit each side (if the mach ine there areft-Wo convenient packaging.

it *Willbeunderstood by those skilled in "the *art that in the-manufectnre of pa'per boxes certain 'gluein'g machine's "deliver l-arge quantities of boxes 1 a :set up condition. "The-space. occupietPby these boxes is so great tlr'atl'means'm ustbc provided to 'flattenthe 'boxesf so as --'to more conveniently ship them, "and when flattened .ithey' mi ist be assembled in--arsliitablereceptacle tohold forshipment. I

Another object 0f the invention is to produce a very rapidly opera-ting machine, the *-box being carried forward without a l I V opening to receive --'a slotted slide box 34 stop and when collapsed being at the sa ne 80 "time forced forward more rapidlyunderthe -rolls for completely flattening it.

plates and prevent the plate 46 from accidentally rising and interfering with the for ward movement of the boxes.

The shaft 32 has a crank pin 56 on its outer endwhich is connected to the pitman 64; The'other end of the pitman 64 is connected-to an arm 65 on the end of the transverseshaft 66 and-this shaft has two 7 curved arms 67, 68 which are arranged to press theboxes forward as they are pushed down into the receptacle for them. On the" inside of the plates 6 and 7 there are two short fiat springs 69, 69 fastened in place at one end only, the object of which is to hold. a

the boxes in the position they are pushed into by the operation of the arms 67, 68.

The rollers 47, 48 are rotated continuously by the belt 70 running over the pulleys 71, 7 2 and gears 7 3, 74 insure the positive drive of each roller.

The boxes when carried through the rollers strike a curved guideplate 7 5 near which a rapidly running pulley 76 is placed to aid in pushing the'boxes down into the receptacle without allowing them to spring open again. The pulley 76 is secured to. a shaft 77 driven by the belt 78passing around two pulleys 7 9, 80. The shaft77 is journalled in two boxes 81, 82 'carried'by .the sides of the machine.

is bolted to the base 3 as shown at 7 5.

The operation of the machine is as follows: The boxes are fed into the space be tween the two belts 22, 23 on the floor formed by the series of rollers from. any suitable source of supply with the long'coven flap extending up on the forward edge of The belts carry the box down till the box contacts with the roller 47 whereupon the plate 46 begins to move up to fold down the back edge of the box. The timing is so arranged that the box is kept in motion all the time, the pres sure on the back of the box tendingto move forward under the rollers and at the same time as the folding operation is taking place the cam 45 is pushing thebox under the The guide plate corner cut off while the plate 46 has both corners cut off. The object of this is to allow for the diagonal creasing of the box corners, the 'sides'folding over the top of the plate 46. I r 7 When the rollers 47, 48 take the box they completely flatten it and push it down into the receiving receptacle the pulley 76 and rod 75 holding it straight.

hen the box is being pushed down into the receiving receptacle the arms 67', 68 are in the dotted line position Fig. 1, but as soon as the-box drops, on the bottom they return and push the box up so the springs 69, 69 hold them in a solidly packed bundle.

The receptacle forthe flattened boxes may be made as long as desired to suit the convenience of the operator. E

What I claim is as follows, but modifications maybe made in carrying out the invention shown in thedra'wings and in the above particularly described form thereof, within the purview of the invention;

1; In a box collapsing machine, a box supporting and carrying channel, plates for collapsing the'sides of the box, a pairfo-f rollers, and means whereby one of said plates moves forward as it collapses the box side to push the collapsed box into the rollers. I r v 2. In a box collapsing machine, a box supporting and carrying channel, plates for collapsing the sides of the box'atthe end of the channeh-a pair of rollers and means whereby one oftheside collapsing plates pushes the collapsed box out from under two of said plates into engagement with said rollers. V

In a box collapsing machine, a box supporting and carrying channel, three plates for collapsing the sides of the box, a pair of flattening rollers, and means'toadvance one of said plates as it is collapsing the box side to push the box out from under the other two plates into engagement with said rollers.

4. Ina box collapsing machine, a series of rollers for supporting a box and advancing them, endless belt forming the sides of a channel through which the boxes are advanced over the rollers,-plates for'collapsing the sides of the box, a pair of fiattening rollers, and means to advance one of said plates topush the partially flattened box into the rollers 5. Ina box collapsing machine, a box supporting and carrying channelyplates for collapsing the sides of the box, a pair of flattening rollers, a guard to direct the flattened box into a receiving channel, an arm to push the boxes into a given position in said receiving channel and springs to prevent the boxes from returning when pushed into a given position.

6. In a box collapsing machine, a box supporting and carrying channel, plates for collapsing the sides of the box, means whereby one of said plates pushes the collapsed box ahead, a pair of flattening rollers between which the collapsed box is pushed, a receiving channel for the collapsed boxes, a guard to direct the collapsed boxes into said receiving channel, a rapidly running roll against which the boxes bear to aid in taking them away from the flattening rollers, an arm to push the boxes into a given position into the receiving channel turning when pushed into a and springs to prevent the boxes from regiven position in said receiving channel.

7. In a box collapsing machine, a box supportingand carryin channel, three pivoted plates for collapsing the sides of the boxes, a pair of flattening rollers, means to advance one ofsaid plates as it is collapsing the box sideto push the box into one gagement with said rollers, a'gu'ard plate, a rapidly running rollto disengage the box from the flattening rollers, a receiving channel and springs to prevent the boxes from returning when pushedinto a given position in said receiving channel.

In testimony whereof I have hereunto set my hand this 29th day of March A. D. 1923.
